The selection and installation of fire smoke really requires some specific requirements to ensure its effectiveness and safety.The following are some key considerations:
Selection requirements:
1. Performance parameters: When selecting the type, the main consideration is the working temperature, air volume, full voltage, efficiency, noise, motor power, speed and axis power.The selection of these parameters should be based on the specific conditions and smoke drainage needs of the building.
2. Material and structure: The fan should be made of high temperature resistance and corrosion -resistant materials to ensure that it can still run normally under extreme conditions such as fires.At the same time, its structure should be stable and can withstand certain pressure changes.
3. Tobacco discharge capacity: When the temperature of the conveying medium reaches 280 ° C, it can work continuously for 30 minutes, and when the medium temperature is cooled to the ambient temperature, it can still run normally.
Installation requirements:
1. Location and support: The fan should be set on the top of the smoke discharge system, and the air ducts of its import and export should have independent support. The weight of the pipeline shall not be applied to the fan parts.The connection method of the fan should be naturally connected to avoid forcibly connecting.
2. Fire prevention and heat insulation: The ends of both the fan should be sealed by a flexible Grade A non -combustible material, and the A -level non -combustible material should be used under the sealing pad.This helps to prevent corrosion and radiation, and ensure that the fan can be used normally under high temperature and high pressure conditions.
3. Electrical connection: The wiring of the fan must be correct, good ground, and has an independent power supply to ensure that the fan can run normally under any circumstances.
4. Other equipment cooperation: When the fan needs to share the computer room with other equipment, the machine room should be equipped with an automatic water spray fire extinguishing system, and the fan room shall not be set in the machine room for the pipes and pipes used to press the air.
In addition, after the installation is completed, the fan needs to be tried and checked to check whether there are tools and debris inside it, and whether there is too tight or rubbing.Only after strict selection and installation processes can we ensure that fire fire exhaust fan can be effectively evacuated by the safe evacuation of personnel at critical moments.
The above is the specific requirements of the selection and installation of fire exhaust fan
